B22 (Bayonet) base. Also commonly known as the ‘Bayonet’. The most popular B22 or Bayonet fitting is 22mm diameter and with two locating lugs. LED filaments look like a traditional glass light bulb. The yellow strip that provides the light, was created to look like the filament element of the original light bulb. The original LED filament bulb was intended to mimic the appearance of the original Edison light bulb. Made to replace a 30W halogen B22. All our bulbs have been designed to directly replace your old halogens, it truly is as easy as changing a lightbulb! As well as having identical fittings, LEDs can also offer you the same level of brightness as your current bulbs. With our new filament range, we are able to offer different colour temperatures and coatings. Most traditional LED filament bulbs only offer Warm White (2200-2700K) colour temperatures, however, this range allows us to offer you more choice: 2200K (Warm White) – 4000K (Daylight). Choosing dimmable?. Please note, LED lighting does require Trailing Edge technology in order to dim. Please contact us if you’re unsure on your dimmer switch compatibility. 3 year LUMiLiFE warranty.
